摘要：

A semi-preparative high-performance liquid chromatographic procedure on 5-μm silica was developed for the isolation of gram quantities of ethyl trans-5-iodo-trans-2-methylcyclohexane-1-carboxylate (B1) and ethyl trans-4-iodo-trans-2-methylcyclohexane-1-carboxylate (B2) for comparative evaluation as male Mediterranean fruit fly, Ceratitis capitata, attractants and for NMR studies. This procedure can also be used analytically to determine the content of B1 (the attractive isomer) in ceralure, the ethyl 4- and 5-iodo-trans-2-methylcyclohexane-1-carboxylate mixture. 1,1-Dimethylethyl cis-5-iodo-trans-2-methylcyclohexane-1-carboxylate (A) and 1,1-dimethylethyl cis-4-iodo-trans-2-methylcyclohexane-1-carboxylate (C) were isolated and converted to their ethyl esters, thus supplying the four trans-isomers of ceralure. © 1990 Friedr.
